2006-12-13[PATCH] MIPS: Fix COW D-cache aliasing on forkAtsushi Nemoto
Provide a custom copy_user_highpage() to deal with aliasing issues on MIPS. It uses kmap_coherent() to map an user page for kernel with same color. Rewrite copy_to_user_page() and copy_from_user_page() with the new interfaces to avoid extra cache flushing. The main part of this patch was originally written by Ralf Baechle; Atushi Nemoto did the the debugging.

2006-12-13[PATCH] getting rid of all casts of k[cmz]alloc() callsRobert P. J. Day
Run this: #!/bin/sh for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do echo "De-casting $f..." perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f done And then go through and reinstate those cases where code is casting pointers to non-pointers. And then drop a few hunks which conflicted with outstanding work.

More fixes to build breakage from the work_struct changes ... this updates the tps65010 driver. Plus, fix some dependencies related to the way it's used on the OMAP OSK: force static linking there, since the resulting kernel can't link. NOTE that until the i2c core gets fixed to work without SMBUS_QUICK, kernels needing this driver must still use "tps65010.force=0,0x48" on the command line.

These bits are only relevant for cpufreq drivers that use IO ports which are not currently supported by the speedstep-centrino driver.

2006-12-12[IA64] fix possible XPC deadlock when disconnectingDean Nelson
This patch eliminates a potential deadlock that is possible when XPC disconnects a channel to a partition that has gone down. This deadlock will occur if at least one of the kthreads created by XPC for the purpose of making callouts to the channel's registerer is detained in the registerer and will not be returning back to XPC until some registerer request occurs on the now downed partition. The potential for a deadlock is removed by ensuring that there always is a kthread available to make the channel disconnecting callout to the registerer.

2006-12-12[IA64] - Reduce overhead of FP exception logging messagesJack Steiner
Improve the scalability of the fpswa code that rate-limits logging of messages. There are 2 distinctly different problems in this code. 1) If prctl is used to disable logging, last_time is never updated. The result is that fpu_swa_count is zeroed out on EVERY fp fault. This causes a very very hot cache line. The fix reduces the wallclock time of a 1024p FP exception test from 28734 sec to 19 sec!!! 2) On VERY large systems, excessive messages are logged because multiple cpus can each reset or increment fpu_swa_count at about the same time. The result is that hundreds of messages are logged each second. The fixes reduces the logging rate to ~1 per second.

2006-12-12[IA64] Kexec/Kdump: honour non-zero crashkernel offset.Horms
There seems to be a value in both allowing the kernel to determine the base offset of the crashkernel automatically and allowing users's to sepcify it. The old behaviour on ia64, which is still the current behaviour on most architectures is for the user to always specify the address. Recently ia64 was changed so that it is always automatically determined. With this patch the kernel automatically determines the offset if the supplied value is 0, otherwise it uses the value provided. This should probably be backed by a documentation change.

2006-12-12[IA64] CONFIG_KEXEC/CONFIG_CRASH_DUMP permutationsHorms
Actually, on reflection I think that there is a good case for keeping the options separate. I am thinking particularly of people who want a very small crashdump kernel and thus don't want to compile in kexec. The patch below should fix things up so that all valid combinations of KEXEC, CRASH_DUMP and VMCORE compile cleanly - VMCORE depends on CRASH_DUMP which is why I said valid combinations. In a nutshell it just untangles unrelated code and switches around a few defines. Please note that it creats a new file, arch/ia64/kernel/crash_dump.c This is in keeping with the i386 implementation.

2006-12-12[MIPS] Discard .exit.text and .exit.data at runtime.Ralf Baechle
While the recent cset 86384d544157db23879064cde36061cdcafc6794 did improve things it didn't resolve all the problems. So bite the bullet and discard .exit.text and .exit.data at runtime. Which of course sucks because it bloats binaries with code that will never ever be used but it's the only thing that will work reliable as demonstrated by the function sd_major() in drivers/scsi/sd.c. Gcc may compile sd_major() using a jump table which it will put into .rodata. If it also inlines sd_major's function body into exit_sd() which gcc > 3.4.x does. If CONFIG_BLK_DEV_SD has been set to y we would like ld to discard exit_sd's code at link time. However sd_major happens to contain a switch statement which gcc will compile using a jump table in .rodata on the architectures I checked. So, when ld later discards .exit.text only the jump table in .rodata with its stale references to the discard .exit.text will be left which any no antique ld will honor with a link error.

Previously we haven't been doing anything with verbose BUG() reporting, and we've been relying on the oops path for handling BUG()'s, which is rather sub-optimal. This switches BUG handling to use a fixed trapa vector (#0x3e) where we construct a small bug frame post trapa instruction to get the context right.
